  • Applications

    Methyl linolenate (CAS 301-00-8) is the methyl ester of α-linolenic acid (C18:3) and is widely used as a FAME analytical standard in GC/GC-MS to profile fatty acids in vegetable oils and fats for quality control, and as a model substrate to study autoxidation, lipid peroxidation, oxidative stability, and antioxidant inhibition mechanisms; in catalysis and biocatalysis it is employed to probe lipase selectivity, transesterification, hydrolysis, and as a precursor to recover ALA; in materials and energy it serves as a bio-based feedstock for biodiesel research (assessing impacts on cetane number, cold-flow, and NOx) and can be epoxidized/oligomerized to yield bio-plasticizers, PVC stabilizers, green solvents, reactive diluents, and UV/alkyd coatings; it is also a starting point for double-bond cleavage (ozonolysis, metathesis) to specialty monomers and diacids, and an intermediate toward surfactants and biodegradable lubricant additives; because it is highly prone to oxidation, it should be stored airtight under inert gas, protected from light and heat, typically with antioxidants; common sources include flaxseed, soybean, and algal oils.
